the county of Oneida, in the State ofNew York, have invented lnew anduseful Imf provements inrPipe Carriers for Railway7 Signal Systems, ofwhich theollowing, taken in connection with the accompanying drawings,is a full7 clear, kand exact descrip-l tion.

This invention relates to hoods for pipe carriers as used moreparticularly in thel operation of railway signals in which` vmotion istransmitted from a tower vor other sta- V,tion to more `or less distantsemaphoresgor `and more particularl ljacent portions of t e pipesagainst ac-Y cumulations of ice, snow and other foreign.

matter which might interferewith the freev operation of the pipes in,their respective.v the pipes -6.- topermit the redueedends vcarriers andat lthe same time to enable the.l protective units to be easily andquickly in-r stalled upon the carriers without in any way interferingwith, the free operation` of the signals through the medium'. of pipesor equivalent connections.- Y Y These pipes are usually supported insuitablecarriers arranged at intervals along the -traek and provide`facilitate the reciprocal. movement. of the pipes in the carriers whichare usually held.

in an upright position uponl suitablevr supports. f K .Y

' .T he main object 1s to protect the carriers pipes and rollers.

f Other .objects and uses' relating to specific parts of the pipecarriers and protectivemeans willfbe brought out in the followingdescription.
